Embodiment Construction

[0074] The specific embodiment of the present invention is a reed (spring leaf) used in a digital geophone. There are two kinds of physical states for the reed peeled off from the whole corroded reed strip, the reed deformed by heat treatment and aging, and the reed deformed by mechanical force. One is that the parts that need to be gold-plated are located on a plane; the other is that the parts that need to be gold-plated are not on a plane (see figure 2, the parts of the deformed reed after heat treatment and aging in the figure that need to be gold-plated are not on the same plane). The method of the present invention is suitable for the coating of the reeds in the above two physical states.

[0075] The first coating method of the present invention can be found in Figure 1 to Figure 4 , including the following steps:

[0076] 1] Cover the dry film on the plate;

[0077] 2] Place at least one reed of any shape on the dry film, where the gold-plated part of the reed fa...

Abstract

The invention relates to a spare part membrane-coating method before partially plating gold on a reed, which overcomes the defects of high cost, incapable batch operation and easy replacement dot generation phenomenon to affect the gold plating effect existing in the prior art. The method comprises the following steps: coating a dry membrane on a flat plate; using and placing at least one reed on the dry membrane, wherein the reed part to be plated with gold faces to the dry membrane upwards; coating an optical-sensitive wet membrane on the dry membrane and the reed part not to be plated with gold; stationary flowing; releasing the dry membrane, the reed and the optical-sensitive wet membrane from the flat plate, stripping the reed and the optical-sensitive wet membrane from the dry membrane onto a metal net, and enabling the reed part to be plated with gold to face to the metal net; drying the metal net, the reed and the optical-sensitive wet membrane together; enabling the optical-sensitive wet membrane to face an optical source to carry out optical fixing; cleaning the dry membrane and the wet membrane remained on the surface of the reed part to be plated with gold; and plating gold on the reed coated with the optical-sensitive wet membrane after being optically fixed. The invention has the advantages of low cost, and the like.

Description

technical field [0001] The invention relates to a partial electroplating method, in particular to a film coating method for bulk parts of a reed before partial gold plating. Background technique [0002] The reed transmits elastic signals. When it has the requirements of both conductivity and wear resistance, gold plating on its surface is a widely used technology. Double-sided gold-plated and single-sided gold-plated technologies are widely used in reeds (springs) used in digital geophones and keyboard reeds in electronic instruments and meters. [0003] The double-sided gold plating process steps are: [0004] 1] Stainless steel or beryllium bronze strip coated with photosensitive dry film or wet film on one or both sides; [0005] 2] exposure; [0006] 3] developing; [0007] 4] Corrosion to form a reed; [0008] 5] Peel off the reed from the corroded reed strip to form reed parts; [0009] 6] Heat treatment aging deformation; [0010] 7] Pickling to adjust the ela...
